【摘要】：目的探讨TCD联合CTA及CT灌注成像在评估颈动脉狭窄或闭塞患者脑血流动力学变化中的价值。方法选取2013年4月至2015年10月94例颈动脉狭窄或闭塞患者为研究对象,选取同期在我院进行体检的健康志愿者94例为对照组,所有患者及志愿者均采用TCD联合CTA及CT灌注成像,比较不同狭窄程度患者与对照组的脑血流动力学变化情况。结果轻度狭窄、中度狭窄、重度狭窄、闭塞患者的两侧大脑动脉平均血流速度分别为(61.09±18.37)c m/s、(5 5.2 6±1 8.6 1)c m/s、(47.28±15.96)cm/s、(41.75±16.22)cm/s显著低于对照组的(69.42±21.55)cm/s(P0.05)。轻度狭窄、中度狭窄、重度狭窄、闭塞患者的达峰时间分别为(8.24±2.39)s、(9.36±2.54)s、(10.17±2.92)s、(10.94±2.75)s显著高于对照组的(7.63±2.12)s(P0.05)。结论颈内动脉狭窄或闭塞与颅内动脉血流动力学、侧支循环管开放情况、脑灌注参数等密切相关,TCD联合CTA及CT灌注成像可以综合评估颈动脉狭窄或闭塞患者的脑血流动力学变化,为制定合理有效的治疗方案提供科学依据。
[Abstract]:Objective to evaluate the value of TCD combined with CTA and CT perfusion imaging in evaluating cerebral hemodynamic changes in patients with carotid artery stenosis or occlusion. Methods from April 2013 to October 2015, 94 patients with cervical movement were selected. Patients with stenosis or occlusion of veins were studied. 94 healthy volunteers who underwent physical examination in our hospital at the same time were selected as control group. All the patients and volunteers were treated with TCD combined with CTA and CT perfusion imaging. The changes of cerebral hemodynamics in patients with different degree of stenosis were compared with those in control group. Results mild stenosis, moderate stenosis and severe stenosis were observed. The mean blood flow velocities of bilateral cerebral arteries in patients with occlusion were 61.09 卤18.37 c / m / s, 55.26 卤18.61 鈩，
